The biggest challenge when it comes to study mortality at oldest ages is data of reliable quality being rare, data of good quality at individual level are even more sparse. With newly available high quality individual data from France, Belgium and Quebec, we conduct a study on mortality above age 105 using survival analysis method. A preliminary analysis on French dataset shows a continuous increasing trajectory of death risks with a significant male disadvantage even up to these highest ages and an absence of cohort effect. Further exploration with the help of survival analysis’s toolbox while extending our research to Belgian and Quebec population will grant us broader view on mortality at oldest ages, where little is known and opinions are often diverged.
